A wind turbine blade

Abstract

A first aspect of the invention provides a wind turbine blade comprising an inboard wind turbine blade portion and an outboard wind turbine blade portion for joining together by a joint, each of the inboard and outboard wind turbine blade portions having an end with an aerofoil profile, wherein the aerofoil profile has both concave and convex geometric portions, the end of each of the respective wind turbine blade portions having a plurality of inserts embedded therein, each insert comprising an end portion having a connection for coupling the insert to another of the inserts across the joint and an extension portion which extends away from the end portion to a tip, wherein the plurality of inserts of one of the respective wind turbine blade portions includes: at least one first insert; and at least one second insert, wherein the first insert has a geometry different than a geometry of the second insert.
